PHP5接口和PHP5抽象类的语法介绍

大家对具体PHP5抽象类的代码如下：

abstract class AbstractClass {     
   abstract public function test();     
}     
    
class ImplementedClass extends AbstractClass {     
   public function test() {     
       echo "ImplementedClass::test() called. ";     
   }     
}     
    

$o = new ImplementedClass;
